Default Violent shaking

So for a while now my car has been shaky going more than 70mph. I replaced the driver side front hub which was in really bad shape and as soon as I put it on i did a test drive and it felt smooth. a day later it was back to being shaky. Today I was going about 80 and let off the gas and it started shaking violently on the passenger side, the dash looked and felt like it was going to pop out.

The hub feels smooth and fine. any other ideas? I ve been struggling with this issue for a while and I am so hesitant to decide on where to throw my hard earned money. The steering gear feels soo darty and loose too.


how often do i need to balance my tires?

Keep checking suspension parts man. Loose or missing bolts. If all thats fine then i hope some one comes in with better responses lol. Maybe some thing is wrong with your 5th gear?

Have you had the car aligned? Did u check for up and down or side to side play in the front wheels? Check rubber rag join on steering shaft as well.

bushings look fine. all the bolts look fine.

when you say play in the wheel, I can deff feel the road pull and push the steering wheel in my hands when i grip it loosely.

I am not sure of i can adjust the tie rods, they look like they can be shortened and lengthened.

My camber is maxed as far as it will go to the RIGHT and sometimes the car still pulls left.

Jack one side off the ground, then grab the wheel and try to shake it side to side, if theres play in it chances are a tie rod is smoke and u should be able to see the play at the joint. Shake it top to botom and if there is play in it chances are its a balljoint or a wheel bearing. Ball joint would also be visible when u shake the wheel.

Yes dont put the jack under control arm, it should be hanginf free, hack under the frame rails, if u jack the control arm u can't test for bad ball joint.
